ALSA: hda - Move one-time init codes from generic_hdmi_init()

Browse source 
commit 8b8d654b55 upstream.

The codes to initialize work struct or create a proc interface should
be called only once and never although it's called many times through
the init callback.  Move that stuff into patch_generic_hdmi() so that
it's called only once.
